Disp fx of base of unsp MC bone, subs for fx w delay heal

This code describes a fracture of the base of an unspecified metacarpal bone that is displaced, meaning the bone fragments are not properly aligned. The "G" seventh character indicates that the patient is in a subsequent encounter for this fracture, and the healing process is delayed.

Use this code when a patient presents for follow-up care of a previously diagnosed displaced metacarpal base fracture, and the provider documents that the fracture is not healing at the expected rate. This applies to situations where the specific metacarpal (e.g., first, second) is not documented.

• Ensure documentation specifies "displaced" and "delayed healing" for a subsequent encounter.
• Verify that the fracture is at the "base" of the metacarpal.
• If the specific metacarpal is identified, a more precise code from the S62.31- series should be used.
